So, its not impossible, but it does seem like more work than using Flash to boot the board.
Full ACK from me. I would always recommend to use a small NOR FLASH with a full-blown U-Boot for booting from NOR with full DDR2 setup etc. All this will be hard to implement with all the restrictions for booting from PCI (even though I have never done this before, but I suspect that it will be quite as limited as booting from NAND).
But of course there may be reasons to want to boot over PCI ...
Yes, what is the main reason you want to do this? As mentioned above, I recommend to boot from a small NOR FLASH (512kB) and "wait" in U-Boot for the PCI host to provide the OS/application image via PCI.
